Abstract

Purpose : This is a report on the long-term follow-up of patients who had received black diaphragm
intraocular lens implantation after traumatic aniridia.
Methods : This is a retrospective study on the long-term follow-up for more than 50 months of six patients
who had received black diaphragm intraocular lens implantation after traumatic aniridia.
Results : An improvement in visual acuity of more than two letters, according to the Snellan chart, occurred
in three out of six eyes that were available for follow-up studies after an average period of 7 years and 8
months (50-115 months) after the operation, and no visual acuity decline groups were present. Early
complications of black diaphragm intraocular lens implantation consisted of cystoid macular edema and
transient intraocular pressure rise. The complications late occurred included bullous keratopathy in four eyes,
glaucoma in three eyes, and exotropia in three eyes. We performed penetrating keratoplasty in two of the four
eyes suffering from bullous keratopathy, and an Ahmed valve implantation in two of the three eyes suffering
from glaucoma. There were signs of reduced visual acuity in four eyes due to complications of the surgery.
Conclusion : The authors of this report recommend care in use of black diaphragm intraocular lens
implantation, by studies done with an average follow-up period of 7 years and 8 months post operatively.
Also reported were severe complications with this treatment such as bullous keratopathy and glaucoma.
